The adoption of the proposed extension would allow scientists to share not only data in a comprehensive way but, as importantly, software designed with the extension as a basis. BIDS data ideally contains sufficient information to determine the correct processing method to use for a given combination of parameters. This is modularised in the form of BIDS Apps [1]}, container instances representing whole or sections of processing pipelines. These are controlled using a uniform syntax, permitting the construction of automated processing systems, which may operate on multiple modalities in a dataset. BIDS apps are supplied as both Docker and Singularity containers, facilitating small- and large-scale processing of datasets (e.g., [2]}, [3]}, or [4]}).
